Pass all parameters to component, or obtain in mount method

What would be the recommended approach for hydrating properties in a component. Pass them to the component, or let the component obtain them in the mount method?

For example:

Option 1

@livewire('component', ['paramA' => '...', 'paramB' => '...'])

Option 2

@livewire('component', ['paramA' => '...'])

public function mount($paramA)
{
  $this->paramB = $paramA->relationship()->get();
}
